Notes:1) State Government agencies and commercial sources provided base data.2) The Reserves and Production Division, Office of Oil and Gas, EIA has reviewed and edited inaccurate production data.3) To be consistent between states a GOR of 6,000 (cf/bbl) for each years production was used to classify wells. If the GOR was less than 6,000 (cf/bbl) the well was classed an oil well, greater than or equal 6,000 (cf/bbl) were gas wells.4) To determine production rate brackets for the first and last year of a wells life the annual production was divided by the number of days in the productive months. For other years the annual production was divided by 365 or 366 days.5) Gas volumes have been converted from the various state pressure bases to the Federal base (14.73 psia).

Notes:1) State Government agencies and commercial sources provided base data.2) The Reserves and Production Division, Office of Oil and Gas, EIA has reviewed and edited inaccurate production data.3) To be consistent between states a GOR of 6,000 (cf/bbl) for each years production was used to classify wells. If the GOR was less than 6,000 (cf/bbl) the well was classed an oil well, greater than or equal 6,000 (cf/bbl) were gas wells.4) To determine production rate brackets for the first and last year of a wells life the annual production was divided by the number of days in the productive months. For other years the annual production was divided by 365 or 366 days.5) Gas volumes have been converted from the various state pressure bases to the Federal base (14.73 psia).

Notes:1) State Government agencies and commercial sources provided base data.2) The Reserves and Production Division, Office of Oil and Gas, EIA has reviewed and edited inaccurate production data.3) To be consistent between states a GOR of 6,000 (cf/bbl) for each years production was used to classify wells. If the GOR was less than 6,000 (cf/bbl) the well was classed an oil well, greater than or equal 6,000 (cf/bbl) were gas wells.4) To determine production rate brackets for the first and last year of a wells life the annual production was divided by the number of days in the productive months. For other years the annual production was divided by 365 or 366 days.5) Gas volumes have been converted from the various state pressure bases to the Federal base (14.73 psia).

Notes:1) State Government agencies and commercial sources provided base data.2) The Reserves and Production Division, Office of Oil and Gas, EIA has reviewed and edited inaccurate production data.3) To be consistent between states a GOR of 6,000 (cf/bbl) for each years production was used to classify wells. If the GOR was less than 6,000 (cf/bbl) the well was classed an oil well, greater than or equal 6,000 (cf/bbl) were gas wells.4) To determine production rate brackets for the first and last year of a wells life the annual production was divided by the number of days in the productive months. For other years the annual production was divided by 365 or 366 days.5) Gas volumes have been converted from the various state pressure bases to the Federal base (14.73 psia).
